20.2.2. Key Business Requirements

✅ Key Business Requirements ● Users can add multiple products to the cart ● Cart contents are saved across sessions ● Discounts and promo codes can be applied ● Cart updates dynamically with stock availability ● Checkout process integrates with payment gateway

In the e-commerce cart system, several key business requirements define how the shopping cart feature should operate. First, users must be allowed to add multiple products to their cart, ensuring they can shop for various items in one go. Next, the system should retain cart contents across sessions, meaning that if a user logs out and back in, their selected items should still be there. Additionally, the feature should support the use of discounts and promo codes at checkout, encouraging price-sensitive customers to finalize their purchases. The cart must also update dynamically based on stock availability—if an item is out of stock, the user should be notified. Finally, the checkout process must seamlessly integrate with a payment gateway to ensure secure transactions.

Consider shopping at a physical store. When you put items in your cart and go to checkout, it’s essential that the checkout process reflects any discounts you have (like a coupon), and if an item is out of stock, it has to notify you quickly so you can adjust your purchase. This mirrors how the e-commerce system needs to function online.

✅ Key Business Requirements ● Patients can search doctors by specialty, location, availability ● Doctors can accept or reject appointment requests ● Automatic SMS/email reminders before appointments ● Admin dashboard for scheduling rules and blackout dates

The healthcare appointment system has its set of critical business requirements. Firstly, patients should be able to search for doctors based on various criteria, such as their specialty, location, and availability, allowing for personalized matching. This is important for ensuring patients can find suitable medical help quickly. Secondly, doctors must be given the option to accept or reject appointment requests, which helps in balancing their schedules. To improve patient compliance, there will be automatic reminders sent through SMS or email before appointments. Finally, an admin dashboard is needed for managing scheduling rules and blackout dates—days when doctors may not be available for appointments.

Think about booking a table at a restaurant. You often look up different restaurants (search by specialty and location) and see if there is availability. You might also receive a text or email reminder confirming your reservation. Similarly, the healthcare system streamlines this process for both patients and doctors.

✅ Key Business Requirements ● Users can apply for a loan with ID and income documents ● System auto-calculates eligibility based on rules ● Risk engine flags high-risk applications ● Integration with credit bureaus (e.g., CIBIL) ● Application tracking via dashboard

In the banking loan application portal, several key business requirements outline how users will interact with the system. First, users should be able to apply for a loan by submitting identification and income documents, which is fundamental for ensuring legitimacy in the lending process. The system needs to automatically calculate the user's eligibility for a loan based on pre-set rules, making the process faster and more accurate. There is also a risk engine feature that identifies and flags high-risk applications for further review, ensuring the bank mitigates potential financial losses. Furthermore, the portal must integrate with credit bureaus to retrieve credit histories, such as from CIBIL, to aid in decision-making. Finally, users should have access to a dashboard where they can track the status of their loan applications.

Imagine applying for a loan at a bank's branch. You bring documents to prove your identity and income. The bank quickly checks your creditworthiness, often using a credit score. Similarly, an online loan application streamlines this process, allowing you to see where your application stands, just like tracking an online order after purchasing.
